Future collider experiments will continue to rely on large area gas based detectors for the detection and measurement of muons. These detectors will have to cover active areas of a few thousand square meters. The majority of the large components of these detectors will most likely be produced by industry in reliable and efficient mass production.

To complement the ongoing research in the field of gaseous detectors, where promising technologies are explored on the basis of small prototypes, R&D in the EP Department will focus on scaling up these prototypes to full size muon detectors.

Considered technologies are GEMs, MicroMegas or the new µRWELL. Simulation studies will drive the detector design and will be used to understand the results obtained. The evaluation of a technology will be based on the achieved (long-term) performance in test beams, irradiation and cosmic stands. The comparison with small size prototypes will serve as reference of the scaling-up process.
